Cultivating the land-Mpho Twala.

The Bachelor of Community Development qualification offered on the Qwaqwa Campus develops young professionals who are able to work collaboratively with the community to come up with initiatives that build resilience and sustainability. Before obtaining their qualifications, students are required to identify community needs and to come up with viable ways to eradicate these.

It was during this period that Mpho Twala, a recent CommDev graduate, identified a once-thriving community vegetable garden that had been abandoned and subsequently stripped over the years. Further research led her to realise that the soil was still very fertile, and with a bit of work, could once again be revived to become an income-generating business. She received her qualification during the April graduations on the Qwaqwa Campus, but she did not stop there.

Bringing change to the community through vegetable farming

Twala, with no agricultural background, approached the locals for permission to revive the 1-ha garden into a community-owned vegetable garden. “The land has been uncultivated for more than a decade, and after conducting a needs analysis, I didn’t want to leave it like that, because I saw that if I worked with young people, this would help with the high unemployment rate among the youth in this area,” Twala said.

She says she was driven by bringing about change in her community, which she believes was inspired by her studies.
“I’ve always wanted to do something in my community, and CommDev taught me to see opportunities instead of challenges.”

The vegetable garden currently has 17 employees, 10 of whom are under the age of 35. They are currently harvesting cabbages, various forms of spinach, and white onion – all organic – for home consumption and community purchasing. They also occasionally sell to hawkers around Qwaqwa.

Twala dreams of expanding the garden, adding more crops, and ultimately reaching commercial level. “We are currently classified under subsistence farming – farming for home consumption and selling the surplus so that the project can remain operational. But with the right funding and support, we can grow bigger and better.”

Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
